The analog clock shown in screenshot is from the app named ‘POLYGON ANALOG CLOCKS’.

The Permissions which this theme asks for are to allow the theme to install the Go Launcher Ex in case you don’t have that installed.

To get the best look, turn off the ‘Show Icon Base’ option in Go Launcher. To do so, go to Go Launcher Preferences, select Visual Settings, then select Icons tab, there you can see Show Icon Base option, just turn that off.
